This invention relates to improvements in paper dispensing cabinets.

Broadly it is the object of the invention to provide a novel, simple,and inexpensive mechanism for controlling the feeding of roll paper froma dispensing cabinet in an organization such as to discourage wastefuluse of the paper.

More particularly, it is our object to make the tearing of a sheet fromthe dispensed web a prerequisite to any further feeding of the web whena predetermined delivery has been made. In the two forms of theinvention herein disclosed it is our object as to the preferredconstruction to adapt the cabinet for operation with one hand of theoperator by directly effecting a complete release of the feed mechanismwhen a sheet is torn from the web. In the other form of the deviceherein disclosed the tear-off of the sheet does not release the feedmechanism but merely places another controlled part in condition foroperation on the feed mechanism detent to move it to a releasedposition. In both constructions the severance of the sheet is aprerequisite to the further dispensation of paper. the firstconstruction the tear-olf knife is connected directly with the feedmechanism detent, in the second construction the tear-off has noconnection whatever with the feed mechanism detent and does not operateto release suchv de tent, a separate manual operation being required forthat purpose.

As to both of the devices herein disclosed, it is one of the objects ofthe present invention to require the operator to do more than mereiypull forward on the sheet as a prerequisite to the release of the detentwhichcontrols the feed mechanism. If the cut-off knife as a whole weremounted to oscillate under the roll of paper as a means of detentcontrol, the purpose of the machine might readily be defeated by someperson who, in order to get a double length sheet, would simply tugslightly on the projecting end of the web to release the detent andwould then repeat the operations necessary to the dispensing of a secondlength of web.

In the present device both ends of the tearoff knife are fixed and onlythe central portion of the knife is yieldable so that the operator willbe obliged to make a Very substantial tear transversely of the web inthe direction of complete severance before tripping the yieldableportion of the cut-off knife. When the projecting end of the web hasbeen tugged sufficiently to make the required tear on the stationaryportion of the f knife, it is very difficult to arrest the tearingmovement short of completion. Consequently there is a strong tendency torequire the complete severance of a sheet as a prerequisite to thedispensing of a second length of web, and even if the operator is ableto arrest thetearing move- But whereas in (Cl. 16d-84.5)

Figs. S, 7, 8, and 9 are detail views showin successive positions of acontrol mechanism taken in section through the feed roll shafts andshowing the control mechanism in side eleyation.

Like parts are identified by the same reference characters throughoutthe several views.

The cabinet Ill may be of any desiredconstruction and provided with anysuitable means such as the arm Il for the support of a core I2 uponwhich is wound a roll I5 comprising a web of paper or the like.

The bottom wall 9E of the cabinet is turned upwardly at Il and thenceextends curvilinearly at I8 to the top plate I9 of a paper guidingthroat of which the member 2li constitutes the lower plate. The member2l! is a fixed plate which, as shown in Fig. 2, is serrated at 2l and 22adjacent its opposite ends to constitute the end portions of thetear-olf knife. Between the serrated port-ions 2l and 22 the plate 2Uhas an elongated notch 23 in which there is disposed a yieldabletear-off knife 24 serrated at 25 approximately in line with the serratedportions 2l and 22 of the fixed plate Ztl. The yieldable tear-olf knife1M may conveniently be mounted on a channel 25 which is pivoted topermit the downward yielding of the knife by mounting the channel onlevers 2l and 28 at its ends. These levers, as well as the other partsof the operating mechanism now to be described, are all preferablymounted on a sub-frame of a sub-case 29, whereby to be adapted to bemounted as a unit in the cabinet It).

The lower feed roll 30 is mounted on a shaft 3i journaled in thesub-frame 29 and projecting from the cabinet to provide a crank 32 formanual operation. Coacting with the feed roll 30 is an idling roll tl)about which the paper web 33 is drawn to pass between the idler roll andthe feed roll through the throat comprising plates I 9 and 20 toward thecut-off knife. The rotation of the feed roll will feed the projectingend of the paper web from the cut-off knife about the curved guidesurface I8 to the dispensing slot which lies between the bend I1 of thelower wall and the subframe or sub-case 29.

To control the dispensing operation of the feed roll, crank shaft 3I isprovided at its end with a driving member 35 provided with a singleaxially projecting lug at 36 whereby member 35 constitutes a one toothdriving pinion whereas lug 36 is a single tooth. Member 35 is alsoprovided in its periphery with notches engaged by the pawl 31 againstany backward movement of the crank shaft, thus constraining the crankshaft to rotation in a clockwise direction only, as viewed in Fig. 1 andFig. 3.

Actuated by the single tooth or lug 36 is a driven disk 40 which isfulcrumed at 4I to the sub-frame or case 29 to move pivotally betweenpositions shown in full and dotted lines in Fig. 3. A tension spring 42normally holds member 4U retracted to the position shown in full lines,such position being determined by a stop 43 engaged by the arm 44 ondisk 4U.

Disk 4D has two teeth at 45 and 46 respectively, which are engaged bythe single tooth or lug 36 of the driving disk 35 in the course ofsuccessive rotations of the driving disk. In the full line position ofthe parts' the lug 36 is shown about to engage tooth 45. In moving suchtooth to the first dotted line position lug 36 will clear tooth 45 andthereafter the feed roll will turn for substantially a completerevolution without resistance. The lever 21 which carries the movablecut-off knife portion 24, as previously described, is provided with apawl 41 which engages with teeth 48 and 49 of the driven member 4I] toretain it in the successive positions to which it is impelled byoperation of the tooth or lug 36 of the driving member.

When the driving lug 36 clears tooth 45 just following the initiation ofthe rotation of the feed roll, pawl 41 will engage tooth 48 of thedriven member to hold the driven member in the intermediate dotted lineposition indicated at 44a. After one complete rotation of the feed rollits single tooth or lug 36 Will engage the tooth 46 of the drivenmember, thereby advancing the driven member to its second dotted lineposition as indicated at 441) in Fig. 3. In this position also thedriven member will be retained by pawl 41, engaged, at this time, withtooth 49.

In the meantime the arm 44h will have acted on a detent 50 to oscillatethe detent about its fulcrum 5I against the pressure of spring 52 fromthe full line position shown in Fig. 3 to the dotted line position shownin said figure. In the dotted line position of the detent 56 its iin-ger53 will be disposed in the path of the lug or tooth 36 to restrain suchlug against further rotary movement, thus locking the feed roll against.further delivery of paper.

No further paper delivery can occur until the operator has at leastpartially severed from the web the delivered portion length of paper.The operator grasps the delivered portion of the paper and, pulling fromeither end against the serrated edges 2| or 22 constituting the xedparts of the cut-off knife, the operator begins the tearing of a sheetfrom the web. Not until such tearing has progressed approximately onethird of the distance across the web is the tension required for theseverance of the sheet communicated to the yieldable portion 24 of thecut-off knife. Such tension now causes the yieldable portion of thecut-off knife to oscillate channel 26 and levers 21 and 23 against thepressure of spring 54 to release the pawl 41 of lever 21 from the teethof the driven member 4D, thus permitting such driven member to beretracted by spring 42 to its full line position. The release of thedriven member also releases the detent 5f! which is likewise retractedby its individual spring 52 to its full line position.

The tearing of the sheet from the web, having thus progressed to a pointof substantial severance, will naturally be completed by the operatorand the machine is' left in condition for the dispensing of a secondlength of web upon the renewed manipulation of the crank 32 through thetwo rotations permitted such crank by the control mechanism. Even if theoperator should unnecessarily try to get a double length sheet of paperby partially severing the first sheet in order to trip the release, hewould nevertheless be confronted with the necessity of accepting adouble length sheet having its individual lengths approximately onethird severed. Whether pulls the paper to the right or the left indrawing it on the tear-off knife, he will act on a fixed portion of theknife and consequently will be forced to make a substantial tear beforebeing able to trip the release mechanism.

The fact that the paper sheet is severed from the web at the level ofthe tear-off knife, which is well in the interior of the cabinet, makes'it difficult, if not impossible, for an operator to trip the movableportion of the tear-olf knife except y;

by manipulation of the paper itself. Of course in the broader aspect ofthe invention it is iin-- material at what level the tear-off knife islocated.

In the construction shown in Figs. 4 to 9 the core I2 for the roll I5 ismounted on arms III] which are pivoted Within the cabinet to oscillateon fulerumsl 55, one such arm and fulcrum being illustrated in Fig. 4.The pivoting of arms I I0 allows the weight of roll I5 to rest upon theidler roll 56 which in turn is mounted on arm 51 pivoted to the cabinetat 58, so that the weight is transmitted through the idler roll to themanually operable feed roll 6B carried by the crank shaft 3|.

As in the construction previously described, the tear-off knifecomprises relatively fixed serrated portions 2I and 22 at its respectiveends, such portions comprising a part of a stationary plate 20. Thecentral portion of plate 20 is notched to receive a relatively yieldableplate 24 having a serrated edge at 25 constituting a yieldable portionof the tear-olf knife. The oscillatable plate 24 is mounted foroscillation on a channel 260 carried by lever 210 at one of its ends andby lever 28|] at the other, substantially as in the Fig. l construction.In this device, however, the feed roll is manually conditioned foroperation and the detent controlled by lever 210 simply makes the manualconditioning device ineffective until the detent is released by thetearing of a sheet from the web. The mechanism is best shown in Figs. 6to 9 and is mounted unitarily on the plate 62 which is attached to theinside of the end wall of the cabinet.

As shown in Fig. 6 the detent has been tripped by the tearing off of asheet and the manually controlled mechanism is conditioned for effectiveoperation on the feed regulating mechanism for the release thereof.

The feed roll shaft 3| carries a driving disk 35E! having a projectingpin 36Bl which serves as the single tooth of a one tooth driving pinion.As shown in Fig. 6, the pin 366 is engaged with an unnotched peripheralportion of a driven disk @Eli which prevents the driving disk 35% frommovement in a clockwise direction. Movement counter-clockwise islikewise prevented by means of a pawl 379 engaged behind the pin 36B.

One peripheral portion of driven disk 496 is provided with teeth 63engaged by the complementary teeth of a segment arm iid pivoted at 65 atthe free end of a lever 655 which is normally held retracted by thetension spring 6l to the position shown in Fig. 6. A handle 68 carriedby the lever 65 projects through a slot Et in the mounting plate 52 andthrough the side of the case as shown in Fig. 5. The segment arm 6ft isheld in operative engagement with the teeth 63 of the driven disk 430 bythe tension spring 'ill connected between the lever 66 and said arm.

In this position of the parts it will be apparent that when the handle63 is pushed by the operator toward the rear of the case (to the rightas viewed in Fig. 6) motion will be transmitted from the segment arm Siito the driven disk tijd to oscillate said disk in a clockwise direction,whereby to bring into registry with the path of advance of pin 365] atooth 45@ of the driven disk li.

In the `meantime the last sheet severing movement performed across theedge of the depressible plate portion 25 has caused the shoulder 'Il ofdetent 'l2 to be engaged under tension of spring 'i3 beneath the guideand stop lug 'i4 on plate B2, whereby the detent 'i2 has\held theyieldable portion of the cut-olf knife depressed. Now when the drivendisk 66 was oscillated as above described, its projecting arm 'l5engaged the striker flange 'i6 on the detent to free the detent from thestop 'i6 and allow the detent and the yieldable portion of the tear-offknife to spring upwardly under tension of spring 'I3 to engage the end'i6 of the detent with a notch 'l1 in the end of the segment arm 64,thereby lifting the segment arm free of the teeth 63 and holding suchsegment arm in. an inoperative position against the pin 'i8 as shown inFig. 7.

The handle 68 is now at the back of its slot and therefore can move nofarther in a rearward direction or to the right as viewed in Fig. 7. Theinterlock of the notch of arm i5 with the pin 'i8 will prevent thedetent from yielding to the left and consequently will prevent thesegment arm 6i, lever 66, and handle 68 from moving forwardly or to theleft as viewed in Fig. 7. The manually operable regulating mechanism istherefore inoperable at this time, but the feed mechanism has beenconditioned for operation by the fact that the unnotched periphery ofdisk 453i! has been moved out of the path of pin 36? and the tooth 45thas been moved into such path.

The operator now begins to turn the crank 32 to actuate the feed roll 66in a manner already described. The initial movement of the crank shaft3i turns the driving disk pinion 356 to cause its pin 36H3 to engage thetooth 45) on the driven disk and thereby to actuate the driven disk tothe full line position shown in Fig. 8. After one complete rotation ofthe crank shaft, feed roll, and driving disk, the pin Sf wiil encounterthe second tooth 463.! of the driven disk itil, thereby actuating thedriven disk to the position shown in dotted lines in Fig. 8. Thereafterthe crank shaft, feed roll, and driving pinion may continue theirmovement for substantially another full rotation until the pin 360 againencounters the unnotched portion of the periphery of the driven disk40G. As above explained, the feed roll, crank shaft, and drivingpinionare now locked against rotation in either direction, but the manualresetting mechanism is still held inactive by the detent l2.

The resetting mechanism will remain inactive until the projecting lengthof paper web is pulled across the cutoff knife to tear a sheettherefrom. While the tearing continues across the xed serrated edg'es 2lor 22 of the knife, no release will be effected, but when the tension ofthe tearing sheet is applied to the yieldable portion 24, 25 of thetear-off knife such yieldable portion is caused to yield downwardly,thereby retracting detent "it and allowing the tension spring 'lil topull the notched extremity of the segment arm free of the stationary pin'i8 so that spring 6l can now retract the lever 66 and handle 68. Sincethe detent spring '13, against which the tension of the paper and theyieldable cut-off knife portion 2d, 25 is exerted, acts on a projectingnger of the detent l2, it will be apparent that as the detent is pulledbodily downwardly it is also tilted counter-clockwise as viewed in Fig.9 so that its shoulder portion 'il is re-engaged beneath the stop l,thus restoring the parts to the position shown in Fig. 6, in readinessfor another actuation of the handle to reset the regulating mechanismfor the feeding of an additional length of web.

Thus, in this device, the detent merely holds the manually opera-bleresetting device in its advanced position where it is ineffective toperform its resetting function. When the detent is released by thetear-off of a sheet from the delivered length of web, the manuallyoperable resetting device is returned to its spring-retracted positionfrom which it may again be advanced manually to reset the controlmechanism for permitting the manual delivery 0fA another pr'edeterminedlength of web.
